"Everyone with a Mark has their own mind," he said. "Well, so far as I know. Most everyone else doesn't." He sighed. "If I could explain, I would, but I can't. I can tell you that it's been in place much, much longer than I've had this tattoo, though, and I've played no part in enforcing it." His mouth twitched up into a little smile. "More like the opposite, in case you hadn't noticed."

It was true, he was more than capable of things that she would surely find terrifying; he wasn't even sure if she would approve of the things he did in the name of fighting against the Dark Lord. "I didn't intend to break you out when I first got to know you. I thought it would be easier to stand, being friends with someone that I didn't know as well, didn't trust as much - but you made that difficult." His small smile returned. "You can ask me anything, and I'll answer, if I can. Just make sure you want the answers."
